    Looking for boring log preparation software

    I agree gINT can be hard unless you have a well organized library- I have used Quicklog as an alternative, and like it. Both Quicklog and gINT are available to rent (pay as you go) here...

    Seismic Site Classification

    fatdad said: 'When faced with broad catigories like these, I would not pursue a highly refined field method to see whether you are just barely on the side of "D" or "E". If there was any doubt, I'd just go with "E".' I agree you re: defining site categories with the respect to accuracy of...

    Coefficient of Friction b/w Concrete and Soil

    Phi is an internal friction angle - (phi') is the friction angle under drained cases, (phiT) is the friction under undrained cases. A coefficient of friction for cast-in-place concrete to soil is =tan(0.7*phi') or =tan(0.7*phiT) depending on site conditions & rate of loading.

    Stress Distribution Program

    check out this program, it can model the total and effective stress bulbs from any load data you give it. http://www.rocscience.com/products/Settle3D.asp

    Removal of soil nails

    You may want to talk to your lawer about writing a letter addressing/denying adverse possession. If the nails remain in place (especially if they are part of a structure/wall vs inactive rods in the ground) the current neighbors or any future owner of their land may legally attempt an easment of...

    Pavement Replacement

    I agree w/ civilperson's post. If the change in grade is so great that it cannot be made up with an AC overlay, the existing AC can be ground & recycled. An attachment to a dozer/loader thats essentially a spinning drum w/ teeth will grind AC in place and mix it into your base rock. The area can...

    Spencer vs. Morgenstern Price Methods

    Here is some language on this topic from an ASCE/SCEC document which was created to be a guideline for landslide analysis in Southern California: "The methods of Morgenstern and Price, Spencer, Sarma, Taylor, and Janbu's generalized procedure of slices satisfy all conditions of equilibrium and...

    Retaining Wall support with Rocscience SLIDE

    When I use SLIDE to model MSE walls it is as a check for global stability, and I only model the grid or fabric in the slope (no wall facing). The manufacture's software was used to find the grid length & strength needed for the wall's internal stability. A three foot wall might not even need...

    Logging Software??

    jj After using both quicklog and gINT, I agree with Jeff that CAD might be the best way for the occasional log, it can take a lot of effort to make a templete for logging software that meets everyone satisfaction! I've used gINT in the past thru a site that allows you to 'rent' software. It can...

    Broken Swan Neck on Old Soiltest Direct Shear Apparatus

    Looking at the fractured surface I dont believe that metal would be easily repaired by welding. You may consider shaping two pieces of steel stock to fit snugly either side of the webbing, and using JBweld to glue them in place and the fractured surface back together. JBweld is incredibly...

    Well and Pump vs Tank

    Thanks bimr, I had not considered that a new water district would likly be formed with a common water supply. That is the type of information I'm kinda poking for. RWF7437, I understand that costs vary by location, the dollar amount in your area may not correspond to those here, but would...

    Well and Pump vs Tank

    Thank you guys for the additional replies. We most certainly will be using a local civil to hash out the cruel details. I do find the topic interesing even though it is out of my scope, and would like to know more about what the board has had to consider on your similar projects. I will try to...

    Well and Pump vs Tank

    Thanks for the reply Francesca, I enjoy anecdotes as they often teach a lesson that to that can be difficult to learn first hand. I appreciate the caveat that the sources may differ in quality and possible recharge rates, ect. It may be that we are going to have to use a water tank and common...

    Well and Pump vs Tank

    What are some of the considerations for a water distribition system for 4-13 homes in a rural area. An onsite spring has been measured to provide clean potable water at 60GPM. The two intial designs are (1) pump water from the spring 150 feet up to a possible tank location or (2) use wells do...

    Consol on very soft silts

    Thanks for the all the replies, Bigyak what type of equipment do you refer to as a skip? Contractors around here refer to small clam-shell bucket loaders (around 1yd^3 max)as a skip, I have a feeling the jargon in your location may be different. DDC was considered during our 1st site visit...
